+- [Brad House brought this change]
- ares_set_servers_csv: fixed IPv6 address parsing
+ Travis: add iOS target built with CMake (#378)
- Fixed bug that caused the last part of an IPv6 address to be parsed as
- the port number when the last part is all numeric.
+ Issue #377 suggested that CMake builds for iOS with c-ares were broken. This PR adds an automatic Travis build for iOS CMake.

+- [Fabrice Fontaine brought this change]
+
+ External projects were using non-public header ares_dns.h, make public again (#376)
- ares_parse_a_reply and ares_parse_aaaa_reply both had two \fB instead of
- \fP
+ It appears some outside projects were relying on macros in ares_dns.h, even though it doesn't appear that header was ever meant to be public. That said, we don't want to break external integrators so we should distribute this header again.

+- ares_getaddrinfo(): duplicate hints ai_socktype and ai_protocol into output
+
+ ai_socktype and ai_protocol were ignored from the hints input. They are now
+ duplicated into the output as expected. Currently no sanity checks on
+ proper values are taking place.
+
+ Fixes: #317
+ Fix By: Brad House (@bradh352)
- ares_parse_txt_reply: return a ares_txt_reply node for each sub-string
+- ares_parse_{a,aaaa}_reply could return larger *naddrttls than passed in
- Previously, the function would wrongly return all substrings merged into
- one.
+ If there are more ttls returned than the maximum provided by the requestor, then
+ the *naddrttls response would be larger than the actual number of elements in
+ the addrttls array.
+
+ This bug could lead to invalid memory accesses in applications using c-ares.
+
+ This behavior appeared to break with PR #257

-- [Alexander Klauer brought this change]
+- [Łukasz Marszał brought this change]
- library init: be recursive
+ empty hquery->name could lead to invalid memory access (#367)
- Previously, a single call to ares_library_cleanup() would deinitialise
- the c-ares library, regardless of how many times ares_library_init() was
- called. This behaviour may cause problems in programs linking two or
- more libraries which, in turn, use c-ares. The present commit fixes this
- problem, deinitializing the library only after a number of calls to
- ares_library_cleanup() matching the number of calls to
- ares_library_init().
-
-- [Patrick Valsecchi brought this change]
+ If hquery->name is empty (=="\0"), &hquery->name[strlen(hquery->name)-1] would point to "random" place in memory. This is causing some of my address sanitizer tests to fail.

-
-- [Alexander Klauer brought this change]
+ CAA (Certification Authority Authorization) was introduced in RFC 6844.

+- [Gisle Vanem brought this change]
- ares_cancel(): cancel requests safely
+ Change the mailman links (#358)
- An invocation of ares_cancel() walks through the request list, calling
- the callbacks of all pending requests on a channel. Previously, if such
- a callback added a new request to the channel, the request list might
- not end up empty, causing an abort by assertion failure. The present
- commit ensures that precisely all requests present upon entry of
- ares_cancel() are cancelled, and that adding new requests through
- callbacks is safe.

+ Reorganize source tree (#349)
- Make the headers prefixed with 'ares'.
+ Originally started by Daniel Stenberg (@bagder) with #123, this patch reorganizes the c-ares source tree to have a more modern layout. It also fixes out of tree builds for autotools, and automatically builds the tests if tests are enabled. All tests are passing which tests each of the supported build systems (autotools, cmake, nmake, mingw gmake). There may be some edge cases that will have to be caught later on for things I'm not aware of.

+ Tests should use dynamic system-assigned ports rather than static port (#346)
- it was also wrongly named as internal functions require two underscores
-
-- ares__bitncmp: use two underscores for private functions
+ The c-ares test suite was hardcoded to use port 5300 (and possibly 5301, 5302) for the test suite. Especially in containers, there may be no guarantee these ports are available and cause tests to fail when they could otherwise succeed. Instead, request the system to assign a port to use dynamically. This is now the default. To override, the test suite still takes the "-p <port>" option as it always has and will honor that.

+- Unset members of the addr struct contain garbage values (#343)
- ... and ares__rc4 is turned into a local static function.

+- [Fionn Fitzmaurice brought this change]
+
+ Avoid buffer overflow in RC4 loop comparison (#336)
- - Take into account that 'wc' may return leading spaces.
+ The rc4 function iterates over a buffer of size buffer_len who's maximum
+ value is INT_MAX with a counter of type short that is not guaranteed to
+ have maximum size INT_MAX.
- - Set internationalization behavior variables.
+ In circumstances where short is narrower than int and where buffer_len
+ is larger than the maximum value of a short, it may be possible to loop
+ infinitely as counter will overflow and never be greater than or equal
+ to buffer_len.
- Tor Arntsen analyzed and reported the issue.
+ The solution is to make the comparison be between types of equal width.
+ This commit defines counter as an int.

- Issue: When building a 32bit target with large file support HP-UX
- <sys/socket.h> header file may simultaneously provide two different
- sets of declarations for sendfile and sendpath functions, one with
- static and another with external linkage. Given that we do not use
- mentioned functions we really don't care which linkage is the
- appropriate one, but on the other hand, the double declaration emmits
- warnings when using the HP-UX compiler and errors when using modern
- gcc versions resulting in fatal compilation errors.
+ Some DNS servers intentionally "misuse" the obsoleted CHAOS (CH) qclass to provide things like `version.bind`, `version.server`, `authors.bind`, `hostname.bind` and `id.server`.
- Mentioned issue is now fixed as long as we don't use sendfile nor

-- version: work towards 1.9.2 (at least)
+ Parse SOA records from ns_t_any response (#103)
+
+ Added the capability of parsing SOA record from a response buffer of ns_t_any type query, this implementation doesn't interfere with existing T_SOA query's response as that too is treated as a list of records. The function returns ARES_EBADRESP if no SOA record is found(as per RFC).
+
+ The basic idea of sticking to RFC that a ns_t_any too should return an SOA record is something open for discussion but I have kept the functionality intact as it was previously i.e the function returns ARES_EBADRESP if it doesn't find a SOA record regardless of which response it is parsing i.e. T_SOA or T_ANY.
+
+ Note that asking for T_ANY is generally a bad idea:

- Fix UDP and TCP port byte order in saved options.
+ Parallel A and AAAA lookups in `ares_getaddrinfo` (#290)
- The UDP and TCP port are stored in network byte order in the
- ares_channeldata, but are passed in to ares_init_options() in host byte
- order. Thus we must return them from ares_save_options() in host byte
- order too, or a duplicated channel will convert them again, leading to a
- nonfunctional channel and a mysterious connection refused error from
- ares_gethostbyname(). This breaks ares_dup(), thus the curl easy API
- when c-ares is used by curl, and thus all the curl easy API's users.
+ A and AAAA lookups for ares_getaddrinfo() are now performed in parallel.
+
+ For this change `ares_search` was removed from `ares_getaddrinfo`.
+ Instead `ares_query` in combination with `next_dns_lookup` are
+ doing the suffix search.

+ Adding support for `.onion` addresses which are tested by
+ `TEST_F(DefaultChannelTest, GetAddrinfoOnionDomain)`

+ Apply the IPv6 server blacklist to all nameserver sources, not just Windows (#193)
- This reverts commit b5823d65706af687c0e5110af8f0cfdcd068997d.
+ For #164, I mentioned that it seemed like the IPv6 nameserver blacklist should apply to all OSes. In a mailing list post, @bradh352 agreed and suggested that I file a PR to make it so.
- This patch was not reviewed properly before pushing
+ This moves the blacklist check from being Windows-specific to being a general feature of config_nameservers(), no matter the nameserver source. It also simplifies the ares_ipv6_server_blacklisted() implementation to not parse and re-parse the blacklisted IPv6 addresses from strings on every check. I think they're almost as easy to read as a sequence of hex bytes in an array initializer, and it's definitely less work on each trip through the code.

+ Harden and rationalize c-ares timeout computation (#187)
+
+ * Harden and rationalize c-ares timeout computation
+ * Remove the rand() part of the timeout calculation completely.
+
+ When c-ares sends a DNS query, it computes the timeout for that request as follows:
+
+ timeplus = channel->timeout << (query->try_count / channel->nservers);
+ timeplus = (timeplus * (9 + (rand () & 7))) / 16;
+ I see two issues with this code. Firstly, when either try_count or channel->timeout are large enough, this can end up as an illegal shift.
+
+ Secondly, the algorithm for adding the random timeout (added in 2009) is surprising. The original commit that introduced this algorithm says it was done to avoid a "packet storm". But, the algorithm appears to only reduce the timeout by an amount proportional to the scaled timeout's magnitude. It isn't clear to me that, for example, cutting a 30 second timeout almost in half to roughly 17 seconds is appropriate. Even with the default timeout of 5000 ms, this algorithm computes values between 2812 ms and 5000 ms, which is enough to cause a slightly latent DNS response to get spuriously dropped.
+
+ If preventing the timers from all expiring at the same time really is desirable, then it seems better to extend the timeout by a small factor so that the application gets at least the timeout it asked for, and maybe a little more. In my experience, this is common practice for timeouts: applications expect that a timeout will happen at or after the designated time (but not before), allowing for delay in detecting and reporting the timeout. Furthermore, it seems like the timeout shouldn't be extended by very much (we don't want a 30 second timeout changing into a 45 second timeout, either).
+
+ Consider also the documentation of channel->timeout in ares_init_options():
+
+ The number of milliseconds each name server is given to respond to a query on the first try. (After the first try, the timeout algorithm becomes more complicated, but scales linearly with the value of timeout.) The default is five seconds.
+
+ In the current implementation, even the first try does not use the value that the user supplies; it will use anywhere between 56% and 100% of that value.
+
+ The attached patch attempts to address all of these concerns without trying to make the algorithm much more sophisticated. After performing a safe shift, this patch simply adds a small random timeout to the computed value of between 0 ms and 511 ms. I could see limiting the random amount to be no greater than a proportion of the configured magnitude, but I can't see scaling the random with the overall computed timeout. As far as I understand, the goal is just to schedule retries "not at the same exact time", so a small difference seems sufficient.
+
+ UPDATE: randomization removed.

-- build: add some explicit file references to VS project files
+ Fix DNS server lookup breaking with Android O due to Android removing access to net.dns# system properties. (#148)
+
+ As of Android 8 (Oreo) access to net.dns# has been removed (https://developer.android.com/about/versions/oreo/android-8.0-changes.html). The reasoning given is that it, "improves privacy on the platform". Currently c-ares uses this to get the list of DNS servers.
+
+ Now the only way to access the DNS server list is by using the Connectivity Manager though Java. This adds the necessary JNI code to use the Connectivity Manager and pull the DNS server list. The old way using __system_property_get with net.dns# remains for compatibilty.
+
+ Using the Connectivity Manager requires the ACCESS_NETWORK_STATE permission to be set on the app. Existing applications most likely are not setting this and keeping the previous method as a fallback will at the very least ensure those apps don't break on older versions of Android. They will need to add this permission for Android 8 compatibility.
+
+ Included in the patch are two initalization functions which are required. The JVM must be registered as well as the Connectivity Manager itself. There is no way to get the Connectivity Manager except though Java. Either being passed down to C directly or by passing in an Android Context which can be used to get the Connectivity Manager. Examples are provided in the documentation.

- and invalid, netmasks are used. Fixes are from bind-9.5.3rc1,
- issue also described in the WLB-2008080064 advisory.

- Define HAVE_INET_NET_PTON only when system's inet_net_pton function is IPv6
- capable and is not affected by the WLB-2008080064 advisory.
+ 9478908a490a6bf009ba58d81de8c1d06d50a117 introduced a length check
+ for records parsed by `ares_parse_naptr_reply()`. However, that
+ function is designed to parse replies which also contain non-NAPTR
+ records; for A records, the `rr_len > 7` check will fail as there
+ are only 4 bytes of payload.
+ In particular, parsing ANY replies for NAPTR records was broken
+ by that patch.
- HAVE_INET_NET_PTON_IPV6 is no longer defined nor used.
+ Fix that by moving the check into the case in which it is already
+ known that the record is a NAPTR record.

-- cast arg to isdigit to int
+ On Windows, the c-ares DNS resolver tries first to get a full list of
+ DNS server addresses by enumerating the system's IPv4/v6 interfaces and
+ then getting the per-interface DNS server lists from those interfaces
+ and joining them together. The OS, at least in the way the c-ares
+ prefers to query them (which also may be the only or best way in some
+ environments), does not provide a unified list of DNS servers ordered
+ according to "current network conditions". Currently, c-ares will then
+ try to use them in whatever order the nested enumeration produces, which
+ may result in DNS requests being sent to servers on one interface
+ (hosting the current default route, for example) that are only intended
+ to be used via another interface (intended to be used when the first
+ interface is not available, for example). This, in turn, can lead to
+ spurious failures and timeouts simply because of the server address
+ order that resulted because of the enumeration process.
- Looks like it might silence a warning on Netware build.
+ This patch makes the (safe?) assumption that there is no other better
+ rule to chose which interface's DNS server list should be prioritized.
+ After all, a DNS lookup isn't something "per network"; applications
+ don't look up "these DNS names on this interface and those DNS names on
+ that interface". There is a single resource pool of DNS servers and the
+ application should presume that any server will give it the "right"
+ answer. However, even if all DNS servers are assumed to give equally
+ useful responses, it is reasonable to expect that some DNS servers will
+ not accept requests on all interfaces. This patch avoids the problem by
+ sorting the DNS server addresses using the Windows IPv4/v6 routing tables.
- Signed-off-by: Ben Greear <greearb@candelatech.com>
-
-- remove all uses of uint32_t
+ For example, a request to DNS server C on interface 2 that is actually
+ sent over interface 1 (which may happen to have the default route) may
+ be rejected by or not delivered to DNS server C. So, better to use DNS
+ servers A and B associated with interface 1, at least as a first try.
- Previous fix forgot a few.
+ By using the metric of the route to the DNS server itself as a proxy for
+ priority of the DNS server in the list, this patch is able to adapt
+ dynamically to changes in the interface list, the DNS server lists per
+ interface, which interfaces are active, the routing table, and so on,
+ while always picking a good "best" DNS server first.
- Signed-off-by: Ben Greear <greearb@candelatech.com>
+ In cases where any DNS server on any interface will do, this patch still
+ seems useful because it will prioritize a lower-metric route's (and thus
+ interface's) servers.

+- XCode v8 introduced clock_gettime() for iOS v10. However, it is a weak symbol, which means when earlier iOS versions try to use clock_gettime() it results in a crash due to the missing symbol. Detect this condition and do not set HAVE_CLOCK_GETTIME_MONOTONIC.

+- Adds cmake build system support to C-Ares.
+
+ The patch does not modify any source files, it only adds 3 new files
+ (CMakelists.txt, ares_build.h.cmake, ares_config.h.cmake) which form the
+ build system. I've tried to go through as much of the autotools tests and
+ extracted what I thought was appropriate, though many of the tests aren't
+ as in-depth in CMake as they are for autotools ... it is unclear why some
+ of them exist at all, I'm guessing for legacy systems that CMake probably
+ doesn't support anyhow.
+
+ Building the library, and examples (adig, ahost, acountry) plus installation
+ should work across a large number of tested platforms. The tests have not
+ yet been integrated.

+- api: add ARES_OPT_NOROTATE optmask value
+
+ Fix up a couple of problems with configuring whether c-ares rotates
+ between different name servers between requests.
+
+ Firstly, ares_save_options() returns (in *optmask) the value of
+ (channel->optmask & ARES_OPT_ROTATE), which doesn't necessarily
+ indicate whether the channel is or is not actually doing rotation.
+ This can be confusing/incorrect if:
+ - the channel was originally configured without ARES_OPT_ROTATE
+ (so it appears that the channel is not rotating)
+ - the /etc/resolv.conf file includes the 'rotate' option
+ (so the channel is actually performing rotation).
+
+ Secondly, it is not possible to reliably configure a channel
+ to not-rotate; leaving off ARES_OPT_ROTATE is not enough, since
+ a 'rotate' option in /etc/resolv.conf will turn it on again.
+
+ Therefore:
+ - add an ARES_OPT_NOROTATE optmask value to allow explicit
+ configuration of no-rotate behaviour
+ - in ares_save_options(), report the value of channel->rotate
+ as exactly one of (optmask & ARES_OPT_ROTATE) or
+ (optmask & ARES_OPT_NOROTATE).
+
+ In terms of back-compatibility:
+ - existing apps that set ARES_OPT_ROTATE will continue to rotate,
+ and to have ARES_OPT_ROTATE reported back from ares_save_options()
+ - existing apps that don't set ARES_OPT_ROTATE will continue to
+ use local config/defaults to decide whether to rotate, and will
+ now get ARES_OPT_ROTATE or ARES_OPT_NOROTATE reported back from
+ ares_save_options() rather than 0.
-- - Where run-time error checks enabling compiler option /GZ was used it is now
- replaced with equivalent /RTCsu for Visual Studio 2003 and newer versions.
+- ares_init_options: only propagate init failures from options
- - Compiler option /GX is now replaced with equivalent /EHsc for all versions.
+ Commit 46bb820be3a8 ("ares_init_options: don't lose init failure")
+ changed init behaviour so that earlier errors in initialization
+ weren't lost. In particular, if the user passes in specific
+ options but they are not applied (e.g. because of an allocation
+ failure), that failure needs to be reported back to the user; this
+ also applies when duplicating a channel with ares_dup().
+
+ However, other initialization failures can be ignored and
+ overridden -- in particular, if init_by_resolv_conf() or
+ init_by_environment() fail, then falling back to default values
+ is OK.
+
+ So only preserve failures from the init_by_options() stage, not
+ from all initialization stages.
+
+ Fixes issue 60.

-- Added README.msvc
+- test: fuzzer mode for AFL's persistent mode
+
+ When fuzzing with AFL, if the LLVM-based instrumentation is
+ used (via the afl-clang-fast wrapper), then it is possible to
+ have a single execution of the fuzzer program iterate multiple
+ times over the fuzzing entrypoint (similar to libFuzzer's normal
+ mode of execution) with different data. This is much (e.g. 10x)
+ faster.
+
+ Add code to support this, by checking whether __AFL_LOOP is
+ defined at compile-time.
+
+ Also, shift the code to effectively be C rather than C++.
-- Changed c-ares naming conventions when using MSVC as described in README.msvc
+- test: simplify deps for fuzzer entrypoint
+
+ No need to depend on the rest of the test code (ares-test.h) for
+ the fuzzer entrypoint; this makes the entrypoint slightly simpler
+ to build with LLVM's libFuzzer.
+
+ Also shift the code to effectively be C rather than C++

+
+ Add a test script that runs the fuzzing command over the

+- test: Add corpus of DNS packets
+
+ For fuzz testing it is useful to start from a corpus of valid

-- Jakub Hrozek modified ares_parse_srv_reply() and ares_parse_txt_reply() API

+ configure: check if tests can get built before enabled
- - Fix Dragonfly BSD triplet detection.
+ The current approach for disabling tests is not a good solution because
+ it forces you to pass --disable-tests, rather than auto-detect if your
+ system can support the tests in the first place. Many (most?) systems
+ do not have C++11. This also causes issues when chain-building c-ares,
+ the hosting system needs to be updated to support passing this
+ additional flag if necessary, it doesn't seem reasonable to add this
+ requirement which breaks compatibility.
- - In case the hard-coded knowledge says that getaddrinfo is threadsafe,
- an additional check is done to verify that h_errno is also defined.
- If h_errno isn't defined, we finally assume that it isn't threadsafe.
- Jamie Lokier provided the inspiration for this extra check.
+ This change auto-detects if the system can build the tests and
+ automatically disable them if it cannot. If you pass --enable-tests to
+ configure and the system cannot build them either due to lack of system
+ support, or because cross-compilation is being used, it will throw an
+ appropriate error since the user indicated they really did want the
+ tests.

+ for a UDP retry and repeats the same answer.
- memdebug.h needs access to libcurl's setup.h from libcurl's lib subdirectory
- and also needs access to libcurl's generated curl_config.h
+ Note that ON_CALL and EXPECT_CALL can't be mixed in the same

+ a previously unknown bug in `lookups` initialization code.
- - Adjusted a comment.
+ If there is no lookup configuration in `resolv.conf`,
+ `init_by_resolv_conf` will attempt to read it from other files available
+ on the system. However, some of these files may have restricted
+ permissions (like `600`), which will lead to `EACCESS` errno, which in
+ turn is handled like a fatal error by `init_by_resolv_conf`.
- - Use ARES_SUCCESS literal for successfull completion.
+ However, it sounds illogical that this error should be handled as a
+ fatal. There is a `init_by_defaults` call that overrides `lookups` with
+ default value, and certainly possible absence of lookup information is
+ the reason why this function exists in a first place!
- - Added CVS Id tag.
-
-- Add c-ares DLL resource file to distribution archive

+- test: More initialization tests
-- John Engelhart noticed an unreleased problem relative to a duplicate
- ARES_ECANCELLED error code value and missing error code description.
+- test: Improve containerized test mechanism
+
+ Aim is to ensure that code coverage information can escape the
+ container. To do this:
+ - Enter a new mount namespace too, so that we can...
+ - Bind mount the expected source directory into the container
+ - Share memory with the sub-process so coverage information is
+ shared too.
-- Fix compiler warning: local variable may be used without having been initialized
+- test: Make contained tests easier to write
-- Use *_CHECK_PATH_SEPARATOR_REQUIRED to ensure that *_CHECK_PATH_SEPARATOR
- is only expanded and included once in the configure script.
+- test: Add framework for containerized testing
+
+ On Linux we can potentially use user and UTS namespaces to run a test
+ in a pseudo-container with:
+ - arbitrary filesystem (e.g. /etc/resolv.conf, /etc/nsswitch.conf, /etc/hosts)
+ - arbitrary hostname/domainname.
+
+ Include a first pass at the framework code to allow this, along with a
+ first test case that uses the container.
-- Our _AS_PATH_SEPARATOR_PREPARE override is now m4_defun'd instead of m4_define'd
- due to autoconf 2.64 m4_require'ing it in _AS_SHELL_SANITIZE indirectly through
- _AS_PATH_WALK.
+- test: Use a longer timeout for less flakiness
+
+ Having occasional test failures from timeout before multiple
+ queries can complete, so up the default timeout for the test
+ from 100ms to 1500ms.
-- Fix compiler warning: argument is incompatible with corresponding format string conversion
+- test: Make failure tests more robust
+
+ Different platforms will do different numbers of allocations
+ in the processing of a given API call; just check that the
+ return code is either success or ENOMEM, and free off any
+ returned state in the former case.
+
+ Also cope with ECONNREFUSED as well as ENOTFOUND.
-- Fix potential out-of-bounds read

+
+ Also expand and re-order the setting of environment variables
+ for easier modification.
+
+ test: Add LSAN build to Travis config
-- Remove HAVE_CONFIG_H definition from here,
- CFLAGS from common.dj already defines it.
+- test: Add initial unit tests for c-ares library
+
+ The tests are written in C++11, using the GoogleTest and GoogleMock
+ frameworks. They have their own independent autoconf setup, so that
+ users of the library need not have a C++ compiler just to get c-ares
+ working (however, the test/configure.ac file does assume the use of
+ a shared top-level m4/ directory). However, this autoconf setup has
+ only been tested on Linux and OSX so far.
+
+ Run with "./arestest", or "./arestest -v" to see extra debug info.
+ The GoogleTest options for running specific tests are also
+ available (e.g. "./arestest --gtest_filter=*Live*").
+
+ The tests are nowhere near complete yet (currently hitting around
+ 60% coverage as reported by gcov), but they do include examples
+ of a few different styles of testing:
+
+ - There are live tests (ares-test-live.cc), which assume that the
+ current machine has a valid DNS setup and connection to the
+ internet; these tests issue queries for real domains but don't
+ particularly check what gets returned. The tests will fail on
+ an offline machine.
+
+ - There a few mock tests (ares-test-mock.cc) that set up a fake DNS
+ server and inject its port into the c-ares library configuration.
+ These tests allow specific response messages to be crafted and
+ injected, and so are likely to be used for many more tests in
+ future.
+
+ - To make this generation/injection easier, the dns-proto.h file
+ includes C++ helper classes for building DNS packets.
+
+ - Other library entrypoints that don't require network activity
+ (e.g. ares_parse_*_reply) are tested directly.
+
+ - There are few tests of library-internal functions that are not
+ normally visible to API users (in ares-test-internal.cc).
+
+ - A couple of the tests use a helper method of the test fixture to
+ inject memory allocation failures, using the earlier change to the
+ library to allow override of malloc/realloc/free.
+
+ - There is also an entrypoint to allow Clang's libfuzzer to drive
+ the packet parsing code in ares_parse_*_reply, together with a
+ standalone wrapper for it (./aresfuzz) to allow use of afl-fuzz
+ for further fuzz testing.
-- initial step towards decoupling c-ares from libcurl for DOS
+- test: Add local copy of GoogleMock/GoogleTest 1.7.0
+
+ Don't check in gtest/m4 files, as they are unused and interfere
+ with the top-level configure process.
-- don't ignore these subdirs, they must be removed first
+- doc: Show build badges in README.md
+
+ Note that these URLs will need to be updated if/when the test branch
+ gets pulled into the master repo/branch.
-- Remove DEBUGBUILD symbol definition, is not required for programs using the library.
+- doc: Convert README to README.md
+
+ Gives better display on GitHub
-- DEBUGBUILD symbol definition for debug builds
+- doc: Update in preparation for next release
+
+ Assume 1.11.0 is next (as there are various API additions).
+ Also add myself to AUTHORS.
-- ignore some subdirs
+- build: Allow header compilation by Windows C++ compiler
-- fix comment
+- build: Expose whether symbol hiding is on
+
+ Adding the CARES_SYMBOL_HIDING definition allows the test suite to
+ detect whether internal symbols are available or not.
-- Try to make more clear that --enable-curldebug has nothing to do with --enable-debug for this library.
+- build: Add autoconf macros for C++11 code using pthreads
+
+ Pull in testing macros from the GNU autoconf archive to allow
+ configure scripts to test for and setup use of a C++11 compiler
+ (AX_CXX_COMPILE_STDCXX_11) and the pthreads library (AX_PTHREAD).
+
+ Note that these macros are not used by the main library autoconf,
+ just by the tests (which share the same m4/ directory).
-- Revert last change, it is inappropriate.
+- build: Add a code coverage option
+
+ Configure with:
+ ./configure --enable-code-coverage
+ Show coverage output with:
+ make code-coverage-capture
+
+ Built on m4/ax_code_coverage.m4 from the GNU autoconf archive
+ to provide the macros to check for presence of gcov + lcov;
+ upstream macro modified to:
+ - Remove use of $(AM_DEFAULT_VERBOSITY) , as earlier versions of
+ autoconf (such as the one used by default on Travis) do not have this.
+ - Rather than automatically defining CODE_COVERAGE_RULES to be a set
+ of makefile rules that use ifeq/endif (which is GNU make-specific),
+ instead only define CODE_COVERAGE_RULES if coverages is turned on,
+ and in that case don't use conditionals in the makefile.
-Gisle Vanem (12 Jun 2009)
-- Replace CURLDEBUG with DEBUGBUILD.
+- api: Add entrypoints to allow use of per-server ports
+
+ Add user-visible entrypoints ares_{get,set}_servers_ports(3), which
+ take struct ares_addr_port_node rather than struct ares_addr_node.
+ This structure includes a UDP and TCP port number; if this is set
+ to zero, the channel-wide port values are used as before.
+
+ Similarly, add a new ares_set_servers_ports_csv(3) entrypoint, which
+ is analogous to ares_set_servers(3) except it doesn't ignore any
+ specified port information; instead, any per-server specified port
+ is used as both the UDP and TCP port for that server.
+
+ The internal struct ares_addr is extended to hold the UDP/TCP ports,
+ stored in network order, with the convention that a value of zero
+ indicates that the channel-wide UDP/TCP port should be used.
+
+ For the internal implementation of ares_dup(3), shift to use the
+ _ports() version of the get/set functions, so port information is
+ transferred correctly to the new channel.
+
+ Update manpages, and add missing ares_set_servers_csv to the lists
+ while we're at it
-Yang Tse (11 Jun 2009)
-- when running automake copy missing files instead of symlinking them
+- api: Add ares_set_sortlist(3) entrypoint
+
+ Allow explicit configuration of the channel's sortlist, by
+ specifying a string in the same format as the equivalent
+ /etc/resolv.conf option.
+
+ This allows library users to perform the same configuration
+ that is available via /etc/resolv.conf, but without needing
+ to change that file.
-- Adjusted to take in account that...
+- api: Allow injection of user-specified malloc/free functions
- With the curl memory tracking feature decoupled from the debug build feature,
- CURLDEBUG and DEBUGBUILD preprocessor symbol definitions are used as follows:
+ Add a new ares_library_init_mem() initialization function for the
+ library which allows the library user to specify their own malloc,
+ realloc & free equivalents for use library-wide.
- CURLDEBUG used for curl debug memory tracking specific code (--enable-curldebug)
+ Store these function pointers in library-wide global variables,
+ defaulting to libc's malloc(), realloc() and free().
- DEBUGBUILD used for debug enabled specific code (--enable-debug)
+ Change all calls to malloc, realloc and free to use the function pointer
+ instead. Also ensure that ares_strdup() is always available
+ (even if the local environment includes strdup(3)), and change the
+ library code to always use it.
+
+ Convert calls to calloc() to use ares_malloc() + memset
-- c-ares' --enable-debug --enable-curldebug decoupling follow-up
+- api: Add option to expose some internal functions
+
+ Purely for testing, add --enable-expose-statics option to configure
+ which converts some static internal functions to be externally visible.
-- mention last changes
+- api: Expose the ares_library_initialized() function
-- Remove buildconf.bat from release and daily snapshot archives.

- buildconf.bat is only for CVS tree builds.
+ This also removes a potential leak where later -s options would
+ replace earlier ones without freeing the relevant string.
-- Ensure that buildconf.bat does nothing unless it is used with a CVS checkout.
+- Mark unhittable lines
+
+ Add comments for the benefit of the lcov tool, marking
+ lines that cannot be hit. Typically these are fall-back
+ protection arms that are already covered by earlier checks,
+ and so it's not worth taking out the unhittable code (in case
+ someone changes the code between the two places in future).

+ commit aba0b775ea30 ("Added ares_getnameinfo which mimics the
+ getnameinfo API")
-- For debugging purposes...
+- config_sortlist: free any existing sortlist on (re)alloc failure
- Disable the '-export-symbols-regex' to discard this as the origin
- of link failures related with shared libraries and non-GNU linkers.
+ If we get an allocation failure on 2nd or later entry in the sortlist, the
+ code would return ENOMEM but still leave the initial entries allocated.
+ Ensure that *sortlist is set to NULL whenever ENOMEM is returned.
-- c-ares Makefile.am back to using $(top_builddir) for *_LDADD
+- ares_dup: clear new channel on failure
+
+ If the attempt to transfer IPv6 servers from the old to the new channel
+ fails, the previous code would still return a channel to the user even though
+ an error return code was generated. This makes it likely that users would
+ leak the channel, so explicitly clear the channel in this case.
-- c-ares' -no-undefined and --enable-curldebug adjustments
+- ares_init_options: don't lose init failure
+
+ If (say) init_by_options() fails, the subsequent call to
+ init_by_defaults() was overwriting the return code with
+ success. Still call init_by_defaults() regardless, but track
+ its return value separately
-- Use relative path to built c-ares tree libtool library
+- ares_gethostbyname: don't leak valid-but-empty hostent
+
+ If an AF_UNSPEC query gets a valid response to its AAAA query,
+ but which has no IPv6 addresses in it, then the code chains on to
+ a A record query. However, the hostent from the AAAA response
+ was being leaked along the way (because it gets replaced before
+ the follow-on end_hquery() invocation).
-- John E. Malmberg noticed that the configure script was failing to detect the
- timeval struct on VMS when building with _XOPEN_SOURCE_EXTENDED undefined due
- to definition taking place in socket.h instead of time.h
+- ares_parse_txt_reply: propagate errors from per-substring loop
+
+ If we get an allocation failure when processing a particular substring in a
+ TXT record, that failure is silently lost; fix that by propagating errors from
+ the inner loop to the outer loop.
-- Fix compiler warning: out of bound access
+- process_answer: fix things up correctly when removing EDNS option
+
+ When a server rejects an EDNS-equipped request, we retry without
+ the EDNS option. However, in TCP mode, the 2-byte length prefix was
+ being calculated wrong -- it was built from the answer length rather than
+ the length of the original request.
+
+ Also, it is theoretically possible that the call to realloc() might change
+ the data pointed to; to allow for this, qbuf also needs updating.
+
+ (Both these fixes were actually included in a patchset sent on the mailing
+ list in Oct 2012, but were included with other functional changes that
+ didn't get merged:
+ http://c-ares.haxx.se/mail/c-ares-archive-2012-10/0004.shtml)

+- ares__read_line: clear buf pointer on realloc failure
-- fix compilation on AIX
+- ares_expand_name: check for valid bits in label length
+

+ top two bits (01, 10) are reserved for future use.

+ The problem occurs if at the start of the loop the sockindex is at the

-Daniel Stenberg (4 Aug 2008)
-- - Fix by Tofu Linden:
-
- The symptom:
- * Users (usually, but not always) on 2-Wire routers and the Comcast service
- and a wired connection to their router would find that the second and
- subsequent DNS lookups from fresh processes using c-ares to resolve the same
- address would cause the process to never see a reply (it keeps polling for
- around 1m15s before giving up).
+ Fix lookup with HOSTALIASES set.
- The repro:
- * On such a machine (and yeah, it took us a lot of QA to find the systems
- that reproduce such a specific problem!), do 'ahost www.secondlife.com',
- then do it again. The first process's lookup will work, subsequent lookups
- will time-out and fail.
+ ares__read_line returns ARES_EOF when it reaches the end of the
+ file. This will happen every time when reading to the end of the
+ HOSTALIASES file. Unfortunately single_domain treats this error as
+ being fatal.
- The cause:
- * init_id_key() was calling randomize_key() *before* it initialized
- key->state, meaning that the randomness generated by randomize_key() is
- immediately overwritten with deterministic values. (/dev/urandom was also
- being read incorrectly in the c-ares version we were using, but this was
- fixed in a later version.)
- * This makes the stream of generated query-IDs from any new c-ares process
- be an identical and predictable sequence of IDs.
- * This makes the 2-Wire's default built-in DNS server detect these queries
- as probable-duplicates and (erroneously) not respond at all.

-Yang Tse (22 May 2008)
-- MSVC6+ clean-up targets must also remove acountry.exe
+Daniel Stenberg (5 Mar 2010)
+- Daniel Johnson provided fixes for building with the clang compiler

+Gisle Vanem (5 Mar 2010)
+- Ops!. Readded ares_nowarn.h.
-- fix: remove need and definition of HAVE_SOCKLEN_T symbol
+- Added ares_nowarn.c.
-- fix: socklen_t definition comment
+Yang Tse (28 Feb 2010)
+- Added SIZEOF_INT and SIZEOF_SHORT definitions for non-configure systems
-- update several macros using AC_TRY_LINK with AC_LINK_IFELSE
+- Added ares_nowarn.* to VC6 project file
-- fix underquoting of AC_LANG_PROGRAM arguments
+- Added SIZEOF_INT definition
-- if'def out private function ares__tvdiff(), it is not in use yet.
+- fix compiler warning
-- update several macros using AC_TRY_LINK with AC_LINK_IFELSE
+- fix compiler warning
-- fix socklen_t equivalent detection when cross compiling Windows target
+- fix compiler warning
-- if WINSOCK2 API is used link with 'ws2_32', else
-
- if WINSOCK API is used under WinCE link with 'winsock', else
+Daniel Stenberg (17 Feb 2010)
+- ares_reinit()
- if WINSOCK API is used link with 'wsock32'.
-
-- on winsock systems linking is done using library 'ws2_32' when
- winsock2.h is available, and library 'winsock' is used when only
- winsock.h is available.
-
-- minor change for wince-cegcc and wince-mingw32ce support
-
-- millisecond resolution support followup
-
-Gisle Vanem (15 May 2008)
-- Replaced "-DHAVE_FIONBIO" with "-DHAVE_IOCTLSOCKET".
- Added "-DHAVE_GETTIMEOFDAY". Trimmed lines.
-
-Yang Tse (15 May 2008)
-- sync with reality
+ - To allow an app to force a re-read of /etc/resolv.conf etc, pretty much
+ like the res_init() resolver function offers
-- remove compilation time generated files
+- - Tommie Gannert pointed out a silly bug in ares_process_fd() since it didn't
+ check for broken connections like ares_process() did. Based on that, I
+ merged the two functions into a single generic one with two front-ends.
-- use same time source for timeout initialization and processing
+Yang Tse (30 Dec 2009)
+- VMS specific preprocessor symbol checking adjustments
-- Improve toolchain detection for WinCE cross compilation:
-
- When cross compiling WinCE with the arm-wince-cegcc-gcc C compiler
- symbol __CEGCC__ is defined and the unix-like compatibility layer
- is used. For our purposes this is not a native Windows build.
-
- When cross compiling WinCE with the arm-wince-mingw32ce-gcc C compiler
- symbol __MINGW32CE__ is defined and the unix-like compatibility layer
- is not used. For our purposes this _is_ a native Windows build.
+- Mention last changes
-- skip checks for Windows specific header files
- when build target is not a native Windows one
+- - Fix configure_socket() to use ares_socket_t instead of int data type.
-- WinCE cross compilation adjustments:
+- - Where run-time error checks enabling compiler option /GZ was used it is now
+ replaced with equivalent /RTCsu for Visual Studio 2003 and newer versions.
- HAVE_WINSOCK2_H shall not be defined.
- HAVE_WS2TCPIP_H shall not be defined.
-
-Daniel Stenberg (13 May 2008)
-- - Introducing millisecond resolution support for the timeout option. See
- ares_init_options()'s ARES_OPT_TIMEOUTMS.
+ - Compiler option /GX is now replaced with equivalent /EHsc for all versions.
-Yang Tse (13 May 2008)
-- also ignore this
+- - Ingmar Runge noticed that Windows config-win32.h configuration file
+ did not include a definition for HAVE_CLOSESOCKET which resulted in
+ function close() being inappropriately used to close sockets.
-- also ignore this
+Daniel Stenberg (30 Nov 2009)
+- start working on 1.7.1
-- ignore this compilation time generated files
+Version 1.7.0 (27 Nov 2009)
-- don't keep in CVS this compilation time generated file
+Yang Tse (27 Nov 2009)
+- Preserve empty line following last target
-- add MSVC6 project for acountry sample program
+- - Larry Lansing fixed ares_parse_srv_reply to properly parse replies
+ which might contain non-SRV answers, skipping over potential non-SRV
+ ones such as CNAMEs.
-- update MSVC6 projects to use the multithreaded DLL runtime library
+- When using icc, compile with -fpic and link with intel dynamic libraries.
-- add MSVC6 project for acountry sample program
+- Added 'currently' in italics to insist on transient situation.
-- skip libtool C++ preprocessor compiler and linker checks
+- Fix language
-- ignore libcares.pc
+- Daniel wants upcoming release to be 1.7.0
-- configure script will now define HAVE_CLOCK_GETTIME_MONOTONIC symbol only
- when function clock_gettime() is available and the monotonic timer is
- also available. Otherwise, in some cases, librt or libposix4 could be used
- for linking even when finally not using the clock_gettime() function due
- to lack of the monotonic clock.
+- Mention last changes
-- fix syntax error: missing semicolon
+- - Removed from external interface preprocessor symbol definition for
+ CARES_HAVE_ARES_FREE_DATA. Current functionality of ares_free_data()
+ makes it unnecessary.
-- Add library checking for clock_gettime() support
+- Added README.msvc
-- Use monotonic time source if available.
+- Changed c-ares naming conventions when using MSVC as described in README.msvc
-Daniel Stenberg (9 May 2008)
-- Removed AC_PROG_CC_STDC again. It enforces C99/gnu99 stdandard which is too
- liberal for me. Also, autoconf 2.61 and earlier doesn't work with icc 10.1
- for this macro. (2.62 confirmed to work though). See discusson on the mailing
- list starting here:
-
- http://daniel.haxx.se/projects/c-ares/mail/c-ares-archive-2008-05/0001.shtml
+- - Mention other recent changes
-- include strings.h (if available) for the strcasecmp() proto
+- - Jakub Hrozek renamed addrttl and addr6ttl structs to ares_addrttl and
+ ares_addr6ttl in order to prevent name space pollution, along with
+ necessary changes to code base and man pages.This change does not break
+ ABI, there is no need to recompile existing applications. But existing
+ applications using these structs with the old name will need source code
+ adjustments when recompiled using c-ares 1.6.1.
-- check for strings.h in configure and use it for the strcasecmp() proto
+- - Jakub Hrozek fixed more function prototypes in man pages to sync them
+ with the ones declared in ares.h
-- adjusted to work with the updated configure.ac
+- Make configure remove the ares_build.h file included in distribution tarballs.
-- - Sebastian made c-ares able to return all PTR-records when doing reverse
- lookups. It is not common practice to have multiple PTR-Records for a single
- IP, but its perfectly legal and some sites have those.
+- Fix macro redefinition.
-- - Doug Goldstein provided a configure patch: updates autoconf 2.13 usage to
- autoconf 2.57 usage (which is the version you have specified as the minimum
- version). It's a minor change but it does clean up some warnings with newer
- autoconf (specifically 2.62).
+- Fix name space pollution.
-Yang Tse (5 May 2008)
-- Improved parsing of resolver configuration files
+- Allow using different extra import libraries for debug and release builds.
-- make previous compiler warning fix more portable
+- Add manifest stuff to msvc makefile
-- fix compiler warning: indirection to slightly different base types
+- Sync man page with reality
-- fix compiler warning: local variable may be used without having been initialized
+- Add missing external API decoration for ares_set_socket_callback()
-- fix compiler warning: unreferenced formal parameter
+- Add ares_free_data() man page.
-- fix compiler warning: assignment within conditional expression
+- - Provide in external interface preprocessor symbol definitions for
+ CARES_HAVE_ARES_FREE_DATA as an indication of function availability.
-Daniel Stenberg (4 Apr 2008)
-- - Alexey Simak fixed the VC dsp file by adding the missing source file
- ares_expand_string.c
+- Remove typecast
-- Alexey Simak made adig support NAPTR records
+- Fix comment
-- Eino Tuominen improved the code when a file is used to seed the randomizer
+- Add ares_data.c and ares_data.h
-Yang Tse (29 Feb 2008)
-- Force AIX xlc to fail and not generate object code if the source code has
- compiled with errors. This behaviour is needed for autoconf macros which
- rely on the ability to compile with or without errors, and is safer than
- xlc's default of failing only upon severe errors.
+- Jakub Hrozek modified ares_parse_srv_reply() and ares_parse_txt_reply() API
+ to return a linked lists of results. These were also modified to internally
+ use the ares_data memory struct and as such its result must be free'ed with
+ ares_free_data().
-Gunter Knauf (27 Feb 2008)
-- added get_ver.awk since c-ares is a standalone project, and should therefore also compile when cURL is absent.
+- Initial support for the generic ares_free_data() function that will allow
+ applications to free memory allocated and returned by some c-ares funtions.
-- a couple of small fixes to the makefile:
- fixed comments; fixed INSTDIR define, simplified rules;
- changed to use get_ver.awk in current dir rather than the curl one.
+- Make usage of calloc()'s arguments consistent with rest of code base
-- fixed linker def file for tools when compiled with gcc/nlmconv.
+- workaround icc 9.1 optimizer issue
-- added some files which were missing in release tarballs.
+- Add icc fvisibility bug test
-- updated copyright for new year.
+- Fix icc 9.0 compiler warning: external definition with no prior declaration
-Gisle Vanem (2 Jan 2008)
-- Added '-d' option for Watt-32 debugging.
+- Fix three var names
-Yang Tse (18 Dec 2007)
-- MSVC 9.0 (VS2008) does not support Windows build targets prior to WinXP,
- and makes wrong asumptions of build target when it isn't specified. So,
- if no build target has been defined we will target WinXP when building
- with MSVC 9.0 (VS2008).
+- Add check for assert.h header file
-Daniel Stenberg (11 Dec 2007)
-- build acountry too
+- getaddrinfo is fully thread safe on solaris versions which
+ implement the function even when h_errno is not a macro.
+
+ The h_errno macro test now only done on systems for which there
+ is no hard coded knowledge about getaddrinfo's thread safeness.
-Gisle Vanem (11 Dec 2007)
-- Added acountry.c.
+- Remove files generated on previous buildconf/configure run
-- Added build of acountry.nlm.
+- Remove enable-thread / disable-thread configure option. These were only placebo
+ options. The library is always built as thread safe as possible on every system.
-- Added build of acountry.exe.
+- Refactor how preprocessor symbol _THREAD_SAFE definition is done.
-- Build acountry.exe. Added 'socklen_t' define.
+- Assume that getaddrinfo is thread safe, unless hard coded
+ knowledge says the contrary or h_errno is not defined.
-- Another sample application that returns country-code and
- name from an IPv4-address or host-name. Using the service of
- countries.nerd.dk.
+- Related with the threadsafe capability of getaddrinfo:
+
+ - Constantine Sapuntzakis reported that Darwin 6.0 a.k.a. MAC OS X 10.2
+ and newer have a threadsafe getaddrinfo.
+
+ - Fix Dragonfly BSD triplet detection.
+
+ - In case the hard-coded knowledge says that getaddrinfo is threadsafe,
+ an additional check is done to verify that h_errno is also defined.
+ If h_errno isn't defined, we finally assume that it isn't threadsafe.
+ Jamie Lokier provided the inspiration for this extra check.
-Daniel Stenberg (10 Dec 2007)
-- grrr, the previous commit was meant to properly make sure that we don't
- link any executables when doing debug builds since they kind of assume
- symbols provided by libcurl, but it also wrongly included acountry.c
+- AIX 5.2 and newer have threadsafe getaddrinfo.
+
+ Add some comments to better understand what the regex's pretend to achieve.
-- when building
+- HP-UX 11.11 and later have threadsafe getaddrinfo
-- build ahost and adig by default but don't install them
+- Check if getaddrinfo is threadsafe when function check allows it to be used
-Gisle Vanem (10 Dec 2007)
-- Fix for targets that do have 'struct in6_addr', but which doesn't
- define 's6_addr' as a macro.
+- Renamed fpGetNetworkParams and fpSystemFunction036 to avoid namespace pollution with static library
-Yang Tse (3 Dec 2007)
-- Fix three issues previous cleanup introduces.
+- Add kernel32.lib
-Daniel Stenberg (3 Dec 2007)
-- Erik Kline cleaned up ares_gethostbyaddr.c:next_lookup() somewhat
+- Mention last changes
-- Brad Spencer fixed the configure script to assume that there's no
- /dev/urandom when built cross-compiled as then the script cannot check for
- it.
+- Reinstate copyright symbol lost in previous commit
-- the gethostbyname fix applied here as well
+- Make some strings different in resource file for debug or release builds
-- fix next_lookup() to continue searching even if c-ares failed to load the
- /etc/hosts file, pointed out by Erik Kline:
- http://daniel.haxx.se/projects/c-ares/mail/c-ares-archive-2007-11/0027.shtml
+- Ignore more subdirs
-- Remove the check for libdl since that isn't actually used and it causes
- warnings. Pointed out by Robin Cornelius.
+- Fix compiler warning: conditional expression is constant
-- pkgconfig fix by Andreas Schuldei
+- Sync linker and resource compiler options with Makefile.msvc
-- spellfix
+- Follow Makefile.msvc subdirectory naming scheme, and sync compiler options
-- and we start on 1.5.2!
+- Updated MSVC makefile that allows building dynamic and static
+ c-ares libraries in debug and release flavours.
+
+ Additionally each of the three sample programs is built against
+ each of the four possible c-ares libraries, generating all this
+ a total number of 12 executables and 4 libraries.
-Version 1.5.1 (21 Nov 2007)
+- Test for USE_WINSOCK since it is more restrictive than WIN32
-Daniel Stenberg (21 Nov 2007)
-- change
+- Make header inclusion depend on HAVE_*_H definition
-- oops
+- Remove unneeded preprocessor directives
-- start working on 1.5.1 now
+- Adjust c-ares include paths for memory tracking enabled (--enable-curldebug) builds
-Version 1.5.0 (21 Nov 2007)
+- source files used by sample programs
-Daniel Stenberg (21 Nov 2007)
-- this is what 1.5.0 is
+- Renamed c-ares setup.h to ares_setup.h
-- fill in missing copyrights
+- Adjust include paths to take in account that currently:
+
+ c-ares with --enable-curldebug uses memdebug.h from libcurl's lib subdirectory.
+
+ memdebug.h needs access to libcurl's setup.h from libcurl's lib subdirectory
+ and also needs access to libcurl's generated curl_config.h
-Gunter Knauf (18 Nov 2007)
-- removed now obsolete defines;
- updated external library versions to latest.
+- Undo old temporary change once used for testing purposes
-Steinar H. Gunderson (16 Nov 2007)
-- Fix a double free.
+- Mention many changes
-Yang Tse (15 Nov 2007)
-- Needed now that in6_addr is referenced in ares.h
+- Mention --enable-symbol-hiding configure option
-Steinar H. Gunderson (15 Nov 2007)
-- When looking up in DNS and then in the hosts file, return the error code from DNS if both fail, instead of returning the error code from the hosts file, as today. Patch from the Google tree.
+- Symbol hiding configure options renamed to the hopefully less ambiguous
+ --enable-symbol-hiding and --disable-symbol-hiding as well as related
+ macro names and some internal variables used for them.
+
+ Related configuration file preprocessor symbols named to
+ CARES_SYMBOL_HIDING and CARES_SYMBOL_SCOPE_EXTERN.
-- Return TTL data from ares_parse_{a,aaaa}_reply, if the user is so inclined. Patch from the Google tree.
+- Header inclusion depending on HAVE_* symbol.
+ Fix two typos.
-Yang Tse (8 Nov 2007)
-- Define WIN32 when build target is Win32 API.
- This also defines it for WinCE even though it is a subset of WIN32.
+- Comparison of the Initial revision of this file with ares_parse_a_reply.c
+ shows that this one is actually a modified copy of ares_parse_a_reply.c.
+
+ In order to comply with ares_parse_a_reply.c's M.I.T. license, the old
+ 1998 M.I.T. copyright notice is now also preserved in this file the same
+ as it is done in other ares_parse_*.c files.
-- The only libraries actually needed for sample programs adig and
- ahost are ws2_32.lib and advapi32.lib
+- Add CVS Id tag.
+ Fix identation of some license lines.
-- MSVC versions prior to VS2005 do not complain about portable C functions
+- Add CVS Id tag.
-- Windows build targets have socklen_t definition in ws2tcpip.h but some
- versions of ws2tcpip.h do not have the definition. It seems that when
- the socklen_t definition is missing from ws2tcpip.h the definition for
- INET_ADDRSTRLEN is also missing, and that when one definition is present
- the other one also is available.
+- Fix comment
-Gunter Knauf (22 Oct 2007)
-- removed dependency on gettimeofday() since we use only 1 sec resolution here.
+- In no particular order, changed/fixed all of the following in
+ ares_parse_txt_reply() current version:
+
+ - Fixed a couple of potential double free's.
+
+ - Fixed memory leaks upon out of memory condition.
+
+ - Fixed pointer arithmetic.
+
+ - Setting ntxtreply to zero upon entry for all failure cases.
+
+ - Changed data type to size_t for variables substr_len, str_len and
+ the length member of ares_txt_reply struct.
+
+ - Avoided a couple of memcpy() calls.
+
+ - Changed i data type to unsigned int to prevent compiler warnings.
+
+ - Adjusted a comment.
+
+ - Use ARES_SUCCESS literal for successfull completion.
+
+ - Added CVS Id tag.

+- Add reference for ares_parse_srv_reply.pdf
-Steinar H. Gunderson (16 Oct 2007)
-- Fix a bug where fallback from AF_INET6 to AF_INET would not work properly together with relative search; if you had a search path of .a.com and .b.com, and foo.a.com would return ARES_ENODATA and foo.b.com would return ARES_ENOTFOUND, the lookup would not properly retry with AF_INET as it forgot the first ARES_ENODATA.
+- Add reference for ares_parse_srv_reply docs
-Dan Fandrich (15 Oct 2007)
-- Mention first version with CURLOPT_COPYPOSTFIELDS.
- Don't confuse NUL with NULL.
+- External API function linkage decoration adjustment
-Gisle Vanem (8 Oct 2007)
-- Added needed 'HAVE_*' defines.
+- External API function linkage decoration adjustment
-- 'FD_CLOXEC' is meaningless on MSDOS/Watt-32.
+- Initial step towards the ability to reduce c-ares exported symbols
+ based on the 'visibility' attribute for GNUC and __global for Sun
+ compilers, taking also in account __declspec function decoration
+ for Win32 and Symbian DLL's.
+
+ Introducing configure options --enable-hidden-symbols and

-Steinar H. Gunderson (4 Oct 2007)
-- Removed a piece of redundant code (process_answer already takes care of it).
+- Fix comment
-- Another timeout fix in ares_getnameinfo().
+- Fix spelling
-- Send the timeout count in ares_getnameinfo().
+- Fix Pelles C Win32 target compilation issues
-- Moved the NULL check for channel upwards in ares_destroy().
+- John Engelhart noticed an unreleased problem relative to a duplicate
+ ARES_ECANCELLED error code value and missing error code description.
-- Clarified the comment over ares_cancel.
+- Fix compiler warning: local variable may be used without having been initialized
-Yang Tse (2 Oct 2007)
-- Avoid a segfault when generating a DNS "Transaction ID" in internal
- function init_id_key() under low memory conditions.
+- Use *_CHECK_PATH_SEPARATOR_REQUIRED to ensure that *_CHECK_PATH_SEPARATOR
+ is only expanded and included once in the configure script.
-- Add ares_llist.c and ares_llist.h to MSCV project file.
+- Our _AS_PATH_SEPARATOR_PREPARE override is now m4_defun'd instead of m4_define'd
+ due to autoconf 2.64 m4_require'ing it in _AS_SHELL_SANITIZE indirectly through
+ _AS_PATH_WALK.
-Daniel Stenberg (2 Oct 2007)
-- Fixed the problem where next_lookup would use 'status' uninitialized. Now
- it gets passed the initial value as an argument.
+- Fix compiler warning: argument is incompatible with corresponding format string conversion
-Yang Tse (2 Oct 2007)
-- Avoid inline C99ism, and move c-ares routines for managing doubly-linked lists.
+- Fix potential out-of-bounds read
-Daniel Stenberg (1 Oct 2007)

+- Fix compiler warning: addition result could be truncated before cast to bigger sized type
-Steinar H. Gunderson (30 Sep 2007)
-- Fix a memory leak that I recently inadvertedly introduced.
+- Overhauled ares__get_hostent()
+
+ - Fixing out of bounds memory overwrite triggered with malformed /etc/hosts file.
+ - Improving parsing of /etc/hosts file.
+ - Validating requested address family.
+ - Ensuring that failures always return a NULL pointer.
+ - Adjusting header inclusions.
-- Use ISDIGIT instead of isdigit; fixes a gcc warning.
+- Fix ssize_t redefinition errors on WIN64 reported by Alexey Simak
-- Port the TCP socket fix made in ares_fds() to ares_getsock() as well.
+- more files to ignore
-- Previously, processing a large batch of timeouts was O(n^2) in the number of
- outstanding queries, and processing a DNS response packet was O(n) in the
- number of outstanding queries. To speed things up in Google, we added a few circular,
- doubly-linked lists of queries that are hash-bucketed based on
- the attributes we care about, so most important operations are now O(1).
-
- It might be that the number of buckets are higher than most people would need,
- but on a quick calculation it should only be 100kB or so even on a 64-bit
- system, so I've let it stay as-is.
+- Check if _REENTRANT definition is required to
+ make errno available as a preprocessor macro.
-Gisle Vanem (29 Sep 2007)
-- We should standarise on C comments.
+- Attempt to silence bogus compiler warning: "Potential null pointer dereference"

+- ignore more files
-Steinar H. Gunderson (29 Sep 2007)
-- TCP queries can time out too, not just UDP queries. (Patch from the Google tree.)
+Gisle Vanem (7 Sep 2009)
+- Suppress warnings about unused prototypes in Watt32 and Win32 programs.
-- Read and process as many packets as possible in read_udp_packets, to avoid having to run the entire event loop once per packet. (Patch from the Google tree.)
+- Update email address.
-- There are two different places in write_tcp_data() that advance the send_queue; however, they are slightly different and only the first one properly uses a while loop. Consolidate both into a single function that DTTR. (Patch from the Google tree.)
+- Update my email address. Add ares_config.h as dependency for 'make depend'.
-- Reject names that are longer than 255 characters, to avoid problems with strict or buggy DNS server implementations. (Patch from the Google tree)
+Yang Tse (6 Sep 2009)
+- T_SRV portability check
-- In ares_mkquery, make sure we set buflen and buf to reasonable values if there's an error. (Patch from the Google tree)
+Gunter Knauf (5 Sep 2009)
+- changed includes to match style how we do with all other *.c files.
-- Be stricter about what's a valid IP address in fake_hostent. (Patch from the Google tree.)
+- changed u_int16_t to unsigned short because it is the only place within ares and curl where such a type would be used;
+ also it broke many autobuilds. We should probably introduce an ares_port_t if we want to use a type here.
-- Handle the root of the DNS tree correctly in ares_expand_name.
+Gisle Vanem (5 Sep 2009)
+- Replace 'uint16_t' with 'u_int16_t' since the latter is used in ares.h.
-Daniel Stenberg (28 Sep 2007)
-- today's modifications by Steinar and me
+- Added 'ares_parse_srv_reply.obj'. Added definition of 'u_int16_t'. This is I don't like; we should not depend on such non-universal types in a public header. But this is just a quick fix.
-- Bumped version to 1.5.0 for next release and soname bumped to 2 due to ABI
- and API changes in the progress callback (and possibly more coming up from
- Steinar)
+Daniel Stenberg (4 Sep 2009)
+- - Jakub Hrozek added ares_parse_srv_reply() for SRV parsing
-Steinar H. Gunderson (28 Sep 2007)
-- Unrevert previous 'missing' hunks. They were missing since the patch is still in for review :-)
+Steinar H. Gunderson (27 Aug 2009)
+- Support lookup of IPv4 literals in ares_gethostbyname(), even when the address family is set to AF_INET6.
-- Yet more missing hunks... Nggh.
+Gisle Vanem (3 Aug 2009)
+- Remove call to LoadLibrary(). (leftover from debugging).
-- Always register for TCP events even if there are no outstanding queries, as the other side could always close the connection, which is a valid event which should be responded to.
+- Fix bad sentence.
-- Forgot to include a few hunks from ares_process.c earlier. Fixing now.
+Daniel Stenberg (3 Aug 2009)
+- - Timo Teras changed the reason code used in the resolve callback done when
+ ares_cancel() is used, to be ARES_ECANCELLED instead of ARES_ETIMEOUT to
+ better allow the callback to know what's happening.
-- Support a few more socket options, and refactor the option setting a bit. (Patch from the Google tree.)
+- - Joshua Kwan fixed the init routine to fill in the defaults for stuff that
+ fails to get inited by other means. This fixes a case of when the c-ares
+ init fails when internet access is fone.
-- Make the query callbacks return the number of timeouts that happened during the execution of a query, and update documentation accordingly. (Patch from the Google tree.)

+- test if adding ../lib to includes can fix the current break ...
-- Three fixes in one commit (sorry): a) Take care of the tcpbuf if it ends while queued for transmission, note broken servers and close them in the main loop, and store TCP socket generation number in order not to send the same query twice over the same socket.
+- renamed generated config.h to ares_config.h in order to avoid clashes when libcurl is used with other projects which also have a config.h.
-- Don't skip a server if it's the only one. (Bugfix from the Google tree.)
+Yang Tse (21 Jun 2009)
+- Refactor how libraries are checked for connect() function, follow-up.
-Daniel Stenberg (27 Sep 2007)
-- wrong, revert the previous "fix" and instead check that the fd_set pointer
- is non-NULL before we FD_CLR
+- Refactor how libraries are checked for connect() function,
+ and check for connect() as it is done for other functions.
-- eek, fix the conditions to return on either problem instead of requiring
- both to occur
+Gisle Vanem (20 Jun 2009)
+- Remove unneeded defines.
-- Steinar H. Gunderson fixed: Correctly clear sockets from the fd_set on in
- several functions (write_tcp_data, read_tcp_data, read_udp_packets) so that
- if it fails and the socket is closed the following code doesn't try to use
- the file descriptor.
+- Use select_s() and not select().
-- Steinar H. Gunderson modified c-ares to now also do to DNS retries even when
- TCP is used since there are several edge cases where it still makes sense.
+Yang Tse (19 Jun 2009)
+- sclose() function-like macro definition used to close a socket,
+ now solely based on HAVE_CLOSESOCKET and HAVE_CLOSESOCKET_CAMEL
+ config file preprocessor definitions.
-- Brad House provided a fix for ares_save_options(): Apparently I overlooked
- something with the ares_save_options() where it would try to do a malloc(0)
- when no options of that type needed to be saved. On most platforms, this was
- fine because malloc(0) doesn't actually return NULL, but on AIX it does, so
- ares_save_options would return ARES_ENOMEM.
+- add CloseSocket camel case function check
-- added initial pkg-config file (attempt)
+- check for socket() and closesocket() as it is done for other functions
-Gunter Knauf (20 Jul 2007)
-- added curl include for debug builds.
+- Remove HAVE_CONFIG_H definition from here,
+ CFLAGS from common.dj already defines it.
-Daniel Stenberg (14 Jul 2007)
-- added another SEE ALSO
+- initial step towards decoupling c-ares from libcurl for DOS
-- Brad House's fix to hish a win32 compiler warning
+- don't ignore these subdirs, they must be removed first
-- added Vlad's entire description of his valgrind fix
+- Remove DEBUGBUILD symbol definition, is not required for programs using the library.
-- Vlad Dinulescu fixed two outstanding valgrind reports
+- DEBUGBUILD symbol definition for debug builds
-Gunter Knauf (8 Jul 2007)
-- added better CodeWarrior detection.
+- ignore some subdirs
-- removed some obsolete include paths and defines.
+- fix comment
-- add test for gettimeofday() so that HAVE_GETTIMEOFDAY gets defined.
+- Try to make more clear that --enable-curldebug has nothing to do with --enable-debug for this library.
-- although the check for HAVE_STRUCT_TIMEVAL solved the redefine it is incorrect; lets see if a check for HAVE_GETTIMEOFDAY also works; if gettimeofday() is present then we can assume we have the timezone struct too.
+- Revert last change, it is inappropriate.
-- added check for sys/param.h.
+Gisle Vanem (12 Jun 2009)
+- Replace CURLDEBUG with DEBUGBUILD.
-- trial to catch problem with Daniels cross-mingw ares builds.
+Yang Tse (11 Jun 2009)
+- when running automake copy missing files instead of symlinking them
-- added NetWare CLIB-own header to solve gcc warnings.
+- Adjusted to take in account that...
+
+ With the curl memory tracking feature decoupled from the debug build feature,
+ CURLDEBUG and DEBUGBUILD preprocessor symbol definitions are used as follows:
+
+ CURLDEBUG used for curl debug memory tracking specific code (--enable-curldebug)
+
+ DEBUGBUILD used for debug enabled specific code (--enable-debug)
-- few minor changes to make ares compile for NetWare CLIB architecture.
+- c-ares' --enable-debug --enable-curldebug decoupling follow-up
-- changed to build for CLIB / LIBC.
+- mention last changes
-- sync'd with lib makefile changes: use var for awk; fixed RECV* / SEND* defines; debug var can be overwritten; added better compiler path handling.
+- Remove buildconf.bat from release and daily snapshot archives.
+
+ buildconf.bat is only for CVS tree builds.
-Daniel Stenberg (8 Jun 2007)
-- start working on 1.4.1
+- Ensure that buildconf.bat does nothing unless it is used with a CVS checkout.
-Version 1.4.0 (8 Jun 2007)
+- CVS-INFO file only present in CVS tree, never in release nor daily snapshot
+ archives. Used as a sentinel file in buildconf.bat to differentiate CVS builds.
-Daniel Stenberg (8 Jun 2007)
-- 1.4.0 preps
+Gisle Vanem (8 Jun 2009)
+- Update comment about "ML". Removed "-D_USE_32BIT_TIME_T" (not a requirement).
-- the revert
+Yang Tse (8 Jun 2009)
+- just comment it out
-- Revered Ashish Sharma's multiple entries patch, as it caused memory madness
+- For debugging purposes...
+
+ Disable the '-export-symbols-regex' to discard this as the origin
+ of link failures related with shared libraries and non-GNU linkers.
-- minor edit since getting an ID seems pointless when failure happens
+- c-ares Makefile.am back to using $(top_builddir) for *_LDADD
-- fix the bad bad bad mess this caused on name resolves returning more than
- one name... Reported by James Bursa
+- c-ares' -no-undefined and --enable-curldebug adjustments
-- Brad Spencer found and fixed three flaws in the code, found with the new
- gcc 4.2.0 warning: -Waddress
+- Use relative path to built c-ares tree libtool library
-- Brad House fixed VS2005 compiler warnings due to time_t being 64bit.
- He also made recent Microsoft compilers use _strdup() instead of strdup().
+- John E. Malmberg noticed that the configure script was failing to detect the
+ timeval struct on VMS when building with _XOPEN_SOURCE_EXTENDED undefined due
+ to definition taking place in socket.h instead of time.h
-- Ashish Sharma provided a patch for supporting multiple entries in the
- /etc/hosts file. Patch edited for coding style and functionality by me
- (Daniel).
+- Fix compiler warning: out of bound access
